Modern constellations (SpaceX Starshield, Telesat) include ISL. Designing ISL geometry requires managing relative bearing rates between satellites. In LEO, two satellites in adjacent planes can maintain a laser link only if the orbital geometry keeps angular rates below the steering limits of the optical terminals.
This PDF provides a comprehensive guide to mission geometry, orbit and constellation design and management. It covers the principles and applications of mission geometry, orbit and constellation design, and their significance in space mission planning. The PDF includes additional figures, tables, and references. This PDF provides a comprehensive guide to mission

Mission Geometry: Orbit and Constellation Design and Management
The keyword "management" is evolving. With constellations of thousands of satellites (Starlink, Kuiper, China’s GW), manual management is impossible. Future PDFs on this topic will focus on:
